BACKGROUND

1. Field

The present invention relates, generally, to building construction apparatus and methods. More particularly, the invention relates to building tools or accessories, and to methods of using such tools or accessories by carpenters or workers. Most particularly, the invention relates to a shim system, apparatus and methods. The invention is especially suitable for use in installing doors, windows and other building elements in new or existing construction.

2. Background Information

A shim is a thin and often tapered or wedged piece of material, used to fill small gaps or spaces between objects. Shims are typically used to support, adjust for better fit, or provide a level surface for doors, windows and other building elements. In carpentry or joinery, shims are typically small pieces of wood which are inserted into spaces or gaps between boards for alignment of doors, windows and the like.

An example use of shims in carpentry is in the installation of a pre-hung door. A pre-hung door is a door that is already hanging in its own frame (jambs). It is a fully self-contained unit. The main parts of a pre-hung door are door slab, hinges, and a frame. Typically, the entire unit (jambs and door) are installed at once. The unit is set it in a preformed opening and shims are used on either side of the head jamb to squeeze the unit into the opening. The hinge-side jamb is made at least level or perhaps a little higher than the strike-side jamb. Shims are inserted underneath the hinge jamb if it is not at least level. With the door open, the hinge-side jamb is shimmed until it is straight and plumb using a level and placement of shims behind the hinges. Typically, a pair of shims points in opposite directions to create a flat surface. Nails are placed through the jamb, through the shims, and into the framing. Next, the door is closed and shimming is placed under the strike-side jamb until there is an even gap between the door and the head jamb (i.e. the head jamb is level). Shims are placed behind the strike-side jamb until it is also straight and plumb. Using the door itself as a guide, shimming is placed until there is an even gap between the door and the strike-side jamb. Nails are placed through the jamb and shims and into the framing. The head jam is then shimmed and secured.

Existing shim technology is believed to have significant limitations and shortcomings. Thus, a need exists for the present invention.

All U.S. patents and patent applications, and all other published documents mentioned anywhere in this application are hereby incorporated by reference in their entirety.

DETAILED DESCRIPTION

The installation of doors, windows and other such building elements or features, involves placing the element into a rough opening in the construction. The construction may be new or remodel and it may be residential, commercial or industrial. After placement, the element must be oriented so that it is plumb, level and square. This almost universally involves adjustment and securement by using shims, typically wedge shaped wooden shims. The shims are placed between the rough opening framing member (i.e. stud) and the frame (i.e. jamb) of the element.

The present invention provides a technology for improving the shimming process by way of a holder for such shims or, in some embodiments, an adjustable shim assembly.

FIG. 1 shows an embodiment of a shim holder 10 of the present invention. The shim holder 10 has a body which is unitary and preferably thin, substantially flat in a normal state, and flexible. The body is preferably constructed of a flexible plastic material.

The body 10 includes a center panel or region 11, a pair of middle panels 12 a and b, and a pair of outer or end panels 13 a and b. The middle panels 12 are separated from the center panel 11 by slots or channels 20 a and b in the side (relative to the drawing in FIG. 1). Channels 20 a and 20 a′ (prime) are preferably aligned with each other and extend equidistantly from the sides, as do the channels 20 b and 20 b′. Regions or area 21 a and b between the slots 20 couple the center panel 11 to the middle panels 12. The outer or end panels 13 are separated from their respective middle panels 11 by slots or channels 25 a and b in the side (relative to the drawing in FIG. 1). Regions or area 26 a and b between the slots 25 couple the center panel 11 to the middle panels 12. Slots 25 are also preferably aligned and of equivalent dimensions. Slots or channels 30 a and b are preferably disposed in middle panels 12 a and b respectively. The slots 25 are preferably centered in the panels 12.

The side of the body shown in FIG. 1 has adhesive members 13 a and b disposed on the outer panels 13 a and b respectively. The opposite side of the body (not shown) may optionally have one or more adhesive members.

The body 10 and panels 11-13 are shown to have rectangular configurations with substantially rectilinear (straight line) peripheral edges and radiused corners. In the embodiment shown, preferred dimensions are as follows. Other dimensions may be used by those skilled in the art and are within the purview of the invention.

“A” 1½ inches (in.) (2.0 cm.) B ⅞ in. C 10/16 in. D 1/16 in. E 1/16 in. F 1⅛ in. G 2¼ in H 3⅜ in. I 9/16 in. J 9/16 in. K R ⅛ in. L R 1/32 in. M ¾ in. N ¾ in. X 4½ in. Y 4½ in.

FIG. 2 is a front view of another embodiment of the shim holder 100. It is constructed and arranged substantially similar to the shim holder 10 of FIG. 1, comprising a body with a center panel 110, middle panels 111 a and b, and outer panels 112 a and b. By way of illustrating alternative, non-limiting, structural dimensions, those for shim holder 100 are as follows.

“O” 4⅜ inches (in.) P 4⅜ in. Q 1½ in. R 1 17/32 in. S 13/16 in. T ⅝ in. U 5/16 in V 5/16 in. W 1 5/16 in. W′ (Prime) 9/16 in.

FIGS. 3A and B illustrates an embodiment of a method 200 of using a shim holder, of the present invention, to install a building element, for example a door 210, in a structure, for example a wall 215. The first step 230 involves selecting a shim holder for example shim holder 10 describe above. The second step of this embodiment of the method involves activating 231 shim holder 10 a by removing release liners 35 to expose adhesive 34 of elements 13 a and b. The shim holder 10 a is then oriented and placed 232 at a predetermined position on the jamb 220 of the door 210. The next step of the process 200 involves loading 233 the holder 10 with one or more shims 225. One shim 225 a is aligned with insertion edge 226 a and moved between the holder body 10 and the jamb 220. The body 10 flexes to create an insertion pocket 227 that accommodates all of the shim 225 a that is inserted by the user. A further shim 225 b may be inserted, wholly or partly, in the opposite direction beginning at edge 226 b. Still further shims or portions of shims may be inserted by the user as necessary or desired leveling.

The process 200 is repeatable for additional shim holders 10 b, 10 c, 10 d and the like at further positions on the jamb 200 as desired by the user. The shims 225 may be adjusted and trimmed as necessary during leveling and door 210 installation. The door 210 may be secured, for example by inserting nails or other fasteners (not shown) through the holders 10 and shims 225 and into the jambs 220. Shimming may be used on one or both vertical jambs or the horizontal jamb.
